摘　　要：仰泳在竞技游泳比赛中占有一定的地位,从历届奥运会仰泳比赛成绩中发现,我国男子仰泳项目与世界水平还有一定的差距。近年来,浙江省游泳运动员徐嘉余的表现较为突出,在2014年5月的全国游泳冠军赛中,他打破了男子100 m仰泳和200 m仰泳的两项全国纪录。目前,对于男子仰泳的运动学研究不多,这些研究中多数是对划水技术和比赛战术的探讨。以2013年全运会,2014年全国冠军赛中男子仰泳运动员徐嘉余100 m仰泳的比赛成绩和技术分析为基础,并与2011年世界游泳锦标赛男子100m仰泳项目前3名运动员的成绩和技术进行对比,利用现场拍摄法,录像观察法,对比分析法,数理统计等研究方法,分析对比出徐嘉余在100m仰泳中,划水效果好,转身和到边技术有所提高,但划频较慢,且途中游的速度稳定性上起伏较大。Backstroke occupies a certain position in the competitive swimming competition. From the backstroke result of previous Olympic Games, we found out that there was still a certain gap between China＇s men＇s backstroke performance with the world level. In recent years, XU Jia-yu＇s performance is more prominent, who broke 2 national records of men＇s 100 m and 200 m backstroke in the National Championship in May in 2014. The number of present stud- ies on the kinematic characteristics of men ＇ s backstroke is not much, the majority of these studies is to explore stroke technique and game strategies. This paper took 100 m backstroke competition performances and technical analysis of men＇s backstroke swimmer XU Jia-yu in the National Games in 2013 and the National Championship in 2014 as basis, then made a comparison on performances and techniques with the top three athletes in 2011 World Champi- onships men＇s backstroke 100 m. Using the method of on-site shooting , video observation , comparative analysis, mathematical statistics, we come to the conclusion that in the 100 m backstroke, XU Jia yu ＇s stroke effect is good, his turn-around and the edge technique has im- proved,but the frequency of stroke is low, and the speed stability is undulating in midway swimming.
